What are quality improvement tools?
Quality improvement tools are standalone strategies or processes that can help you better understand, analyze, or communicate your QI efforts. Examples of QI tools(www.ihi.org) include run charts, process maps, and fishbone diagrams (ihi.org(www.ihi.org)).
What is the basic philosophy of the fishbone diagram?
